UNITED STATES PATENT OFFICE HERBERT GRAY, OF DETROIT, MICHIGAN, ASSIGNOROF ONE-HALF TO FREDERICK ROHNERT, OF SAME PLACE.

SELF-ATTACHING BUTTON.

SPECIFICATION forming part of Letters Patent No.375,065, dated December20, 1887.

(No modelJ To aZZ whom it may concern.-

Be it known that I, HERBERT GRAY, a citizen of the United States,residing at Detroit, in the county of Wayne and State of Michigan,haveinvented certain new and useful Improvements in Self-AttachingButtons; and I do declare the following to be a full, clear, and exactdescription of theinvention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the letters and figures ofreference marked thereon, which form a part of this specification.

This invention relates to that class of buttons known as self-attaching;and it consists in providing the shank of the button with an annularrecess at the free end, which shank is passed through a set ofkey-holeshaped openings formed in a couple of detachable plates, beingthen turned or slightly rotated, whereby the shank of the button becomesfirmly connected to said plates.

The object of this invention is to provide a self-attaching button thatmay be readily attached to or removed from a garment, being simple,durable, and cheap.

The especial features of my invention will be hereinafter fully setforth, and pointed out particularly in the claims. V

In the accompanying drawings, forming a part of the specification,Figure l is a perspective of my improved device. Fig. 2 is a verticalsection taken on the dotted line :0 ac of Fig. 1. Fig. 3 shows thebutton-head and shank. Fig. 4 shows the outer engaging or looking plate.Fig. 5 shows the inner revolving locking'plate. Fig. 6 shows therevolving base-plate. Fig. 7 is a back face view of the plate of Fig. 6.

D indicates the buttonhead; S, the shank made fast thereto. The free endof said shank is provided with an annular recess or channel, a. (SeeFigs. 2 and 8.)

A represents the crown-plate or disk, to which the shank of the buttonis attached. Said plate has a keyhole-shaped opening, Z, through itsface. (See Figs. 1 and 4.) The round portion 5 of said hole is madesufficiently large to receive freely the head of the shank S. Thedistance across the oblong portion 3 of the hole Z is the same as thedistance through the reduced portion of the shank. The periphery of theplate A is turned over, forming an annular lip, f. (See Fig. 2.)

Bis a circular plate smaller in diameter than the plate A, and islocated on the under side of said plate and has on its periphery aseries of lugs, e. (See Fig. 5.) This plate is pro vided with a key-hole-shaped opening, 5, which opening is of the same proportions as the holeZ of the plate A. The round portions 5 of the holes of both plates arenear the periphery of said plates. The ends d of the oblong portion ofsaid holes terminate at or near the center of each plate. (See Figs. 4and 5.) Y

O is the base-plate, which is in the form of a saucer, or concavoconvex. The diameter of this plate is the same as the plate B, and hasin its upturned edges, or periphery a series of notches or channels, t,which are made sulficiently large to freely receive the arms or lugs eof the plate B.

The plates B G are secured to the under face of the plate A by means ofthe flange f. (See Fig. 2.) Said plates are loosely secured to the plateA thereby and allowed to be revolvedbelow the plate A, for the purposehereinafter specified. The under face of the plate G is provided with aseries of swells or projections, a. (See Fig. 7.) Said projections arefor the purpose of engagement with the thumb and finger of the operator,whereby said plate may be caused to revolve. As the plate 0 is revolvedthe plate B also turns with it, as its lugs e are engaged with therecesses t of the plate O. i

The parts are united and secured to a garment as follows: A hole isfirst made through the article to whichthe button is to be attachedsufficiently large to receive the shank -S, which is then passed throughthe hole. The plates A, B, and O, being united, as shown in Fig. 2, areplaced over the projecting end of the shank, so as to allow-the head iof the shank to pass through the portion 5 of the holes Z Z, when saidshank is moved along toward the end dot the channel portion 3 of saidopenings Z Z,'th'us bringing the reduced portion of the shank S intosaid channels. Then by placing the thumb and finger against the swellsor pintles a of the under plate, 0, and revolving or giving said plate aquarterturn, the plate B will be likewise revolved, thereby bringing theslotted part 3 of the open ing Z at right angles to the slotted portion3 of the opening Z, as clearly shown by dotted lines in Fig. 1. (Seealso Fig. 2.) lVhen the plates are so adjusted, the reduced portion a ofthe shank S will be securelyjournaled in the plates A B, said partsbeing united. To detach the button-head and its shank, the plate B isturned back to former position by revolving the plate 0 sufliciently tocause the hole Z of the under plate to register with the hole Z of theupper plate, as shown in Fig. 1, when the shank S is to be moved alongthe necks 3 of said openings until the head i of the shank enters theenlarged portions 5 of said holes, when the head i of said shank may bedrawn from the plates A B, the parts being detached.

It will. be observed from the foregoing that the parts are simple,durable, and cheap, making a button that can be readily attached to orremoved from a garment Without the aid of any other agent or tool.

Having thus fully set forth my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of the button-head and its recessed shank, of theplate A, having the opening Z, the plate B, having a like opening andseries of lugs, e, on its periphery, the plate 0, having the series ofrecesses t, and the plates B O, secured to the plate A by means of theflange or lipf, as and for the purposes specified.

2. In combination with the recessed shank, the plates A B, each having akeyhole-shaped opening communicating with each other, and the plate 0,attached to the former plates, having on its outer face a series ofprojections, a, for revolving the plates B C, substantially as and forthe purposes specified.

In testimony whereof I afiix my signature in presence of two witnesses.

HERBERT GRAY.
